a chick with a hot body and a cute face who is unhealthy internally, whether by high cholesterol, genetic defect, addiction, infection, or other ailment, to the extent that her value as sexual partner is greatly diminished

"Remember that hot chick I brought home from the bar last week?"

"Yeah, you hit that?"

"I wanted to, but it got weird. She had some kind of brittle bone disease so she gave me all sorts of rules about what I could or could not do. Frankly, it was a complete turn-off."
